Referring more particularly to thefdrawings, 2 designates the rails or a-railway track and 3a bindisposed at the side of the I ,track and mounted upon concrete, posts 4,

or other suitable supports. The bin may be of any suitable form and is not to, be limited t to the. illustrated details thereof.

Beneath the track :and extending parallel to the bin is formed. a chute 5 having an inclined bottomwhich extends outward'to a point beyond the track and dischargesfinto apit 7. This pit has vertical sidewalls and an inclined end wall.

A slotted-link 34 which is connectedat one endfto the hinged bottom 33. lin'1its thedownward swing of the bottom, there being a pin formed upon the body of the bucket which extends into the slot jof this link. -It will be obvious that oneor more links may be used for this purpose.

, a Fig; lafterthebucket has been discharged.

The"operation' 'of my invention is as folone" direction to permit movement of the lows: The contents of the car on tracks 2 is discharged into the chute 5. Assuming that the bucket 32 is lowered, then the operator by meansofthe levers '9 and 12 first turns the spout 1O to-the positionshown in dotted lines in Fig. 1 and then raises the cut-E 8. This permits the contents of the chute to be discharged'into-thebucket 82, it being observed that the spout 10, when lowered,

extends over the bucket and discharges into the middle thereof. Justbefore the bucket is filled the cut-off 8is lowered The spout "10 is then raised and the hoisting'drum 28 is then operated 'Winding'up the cable 23 and raising thebucket from the pit 7. WVhen fthebucket, has been raisedto such height that a head'on'the'block 31 is forced into "7 track '18 until the tripping members 43 engage'the upper ends of the bucket latches 37.

The bottom of thebucket will then be released theiveightjof its contents will cause theopening-of this bottom and the contentsvvill be discharged. When the winding drum 28 is released from its'engagement with theclutch and allowedto run free, the

- cou' nter-iveight will cause the carrier to re- 5mm upon the track, and as the bucket returnspthe bucket closer 45 will engage the "bottom'tand close it. When the carrier has I 'fingers' beingrounded 'in' one' direction. A V "spring'461urgesthefingers44to the position shovvnjin full lines-in Fig; f3,."moveinjent in returnedinearly to its normalposition, the

block 31 will be released and-the weight of the bucket will cause the bucket to drop until it isonce more at the bottomof the pit 7, whereupon the operation may be repeated.

It Will be noted that the mechanism used 'by ne is verysimple and positive in its ac- "tion. It doesnot' readily get out of order.

" erators ivill handle the levers 9 and 12 While the other operator will handle the clutch I lever 30. It is obvious, however, that only one operator is absolutely necessary as the hoisting engine maybe disposed sufliciently adjacent the'leve'rs 9 and 12 to permit one operator to handle allthe levers.
